Gold Series 10U GPU server

The Supermicro SYS-A21GE-NBRT-G1 is a 10U rack server built for high-density compute. Dual Intel Xeon Platinum 8570 processors deliver 56 cores each at 2.10 GHz. The system ships with 2.3 TB of DDR5-5600 ECC memory across 32 slots. Eight NVIDIA HGX B200 GPUs provide 180 GB of video memory for large-scale AI workloads.

Hot-swap cooling and dense storage

Fifteen hot-swappable 80 mm fans and four internal 60 mm fans maintain airflow under sustained load. Eight 3.8 TB U.3 NVMe SSDs and two 1.92 TB M.2 NVMe SSDs install directly into the chassis. Eight single-port 400 GbE OSFP connections and one NVIDIA BlueField-3 DPU at 200 Gb/s handle east-west and north-south traffic. Six 5250 W titanium redundant power supplies operate in a 3+3 configuration.

8TB DDR5 ceiling for memory-bound jobs

Maximum supported memory reaches 8 TB when all 32 slots are populated at 2 DPC, running at 4400 MT/s. This ceiling decides whether the platform fits parameter-heavy models or in-memory databases. Buyers who need more than 8 TB of coherent memory must look at multi-node clusters. Systems limited to 1 DPC top out at 4 TB and 5600 MT/s.

Questions about this item

What is the maximum memory speed supported when all 32 DDR5 slots are populated?

When all 32 slots are populated in a 2DPC configuration, the maximum supported memory speed is 4400 MT/s for ECC DDR5 RDIMM modules.

What are the physical dimensions and drive bay requirements for the installed NVMe storage?

The server includes eight 2.5-inch 15mm U.3 NVMe SSDs and two M.2 NVMe SSDs, requiring compatible 2.5-inch drive bays and M.2 slots on the motherboard.

How are the eight NVIDIA B200 GPUs installed, and what is a common installation oversight?

The eight B200 GPUs are pre-integrated on the NVIDIA HGX baseboard; a common oversight is neglecting to verify that the six 5250W Titanium power supplies are fully seated and the 3+3 redundancy mode is active before powering on.
